SQ3481EV-T1-GE3-VB MOSFET Product Introduction
**SQ3481EV-T1-GE3-VB** is a high-efficiency **single P-channel MOSFET**, using **SOT23-6 package**, designed for low-voltage drive applications, with **-30V maximum drain voltage (VDS)** and **-4.8A maximum drain current (ID)**. The **threshold voltage (Vth)** of this MOSFET is **-1.7V**, which enables it to switch quickly at a reasonable drive voltage and is suitable for low-voltage applications. Its **RDS(ON)** is as low as **49mΩ** (at VGS=10V), which effectively reduces switching losses and improves system efficiency.
This MOSFET uses **Trench technology**, which provides low on-resistance and high current carrying capacity while ensuring good performance. Due to its **smallest size SOT23-6 package**, the SQ3481EV-T1-GE3-VB is ideal for electronic devices with compact circuit design and high performance requirements.
